Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

684
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Skeletal Muscle Relaxants: Therapeutic Uses

608
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Direct-Acting Cholinergic Agonists: Therapeutic Uses

841
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

Adrenergic Agonists: Mixed-Action Agents01:28

Adrenergic Agonists: Mixed-Action Agents

838
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine

Background:

  • External cephalic version (ECV) is a procedure to turn a fetus from breech to cephalic presentation.
  • ECV can reduce the need for cesarean sections in women with breech presentations.

Purpose of the Study:

  • To investigate the effectiveness and safety of ritodrine as a tocolytic agent during ECV.
  • To determine if ritodrine influences the success rate and safety of ECV.

Main Methods:

  • A study involving 407 pregnant women with breech presentations without ECV contraindications.
  • Multivariable logistic regression analysis was employed to assess ritodrine's impact on ECV outcomes.

Main Results:

  • The overall ECV success rate was 67.6%.
  • Ritodrine use was significantly associated with higher odds of successful ECV.
  • No increased risk of adverse effects, including fetal heart rate changes, cesarean delivery due to fetal distress, low Apgar scores, or perinatal mortality, was observed.

Conclusions:

  • Ritodrine as a tocolytic agent may enhance the success rate of external cephalic version.
  • The use of ritodrine during ECV appears to be safe, without a notable increase in adverse perinatal outcomes.
